San Antonio -- Emmy-winning actress Ann B. Davis, who became the country's favorite and most famous housekeeper as the devoted Alice Nelson of "The Brady Bunch," died Sunday at a San Antonio hospital. She was 88.

Bexar County, Texas, medical examiner's investigator Sara Horne said Ms. Davis died Sunday morning at University Hospital. Horne said no cause of death was available and that an autopsy was planned Monday.

Bill Frey, a retired bishop and a longtime friend of Ms. Davis', said she suffered a fall Saturday at her San Antonio home and never recovered. Frey said she had lived with him and his wife, Barbara, since 1976.

Emmys for 'Cummings Show'

More than a decade before scoring as the Bradys' loyal Alice, Ms. Davis was the razor-tongued secretary on another stalwart TV sitcom, "The Bob Cummings Show," which brought her two Emmys. Over the years, she also appeared on Broadway and in occasional movies.

Ms. Davis considered her ordinary look an asset.

"I know at least a couple hundred glamour gals who are starving in this town," she told the Los Angeles Times in 1955, the year the Cummings show began its four-year run. "I'd rather be myself and eating." She said she told NBC photographers not to retouch their pictures of her, but they ignored her request and "gave me eyebrows."

Producer Sherwood Schwartz's "The Brady Bunch" debuted in 1969 and aired for five years. But like Schwartz's other hit, "Gilligan's Island," it has lived on in reruns and sequels.

As the "Brady Bunch" theme song reminded viewers each week, the Bradys combined two families into one. Florence Henderson played a widow raising three daughters when she met her TV husband, Robert Reed, a widower with three boys.

In her blue and white maid's uniform, Ms. Davis' character, Alice Nelson, was constantly cleaning up messes large and small, and she was a mainstay of stability for the family. Her face occupied the center square during the show's opening credits. Her love interest was Sam the Butcher, played by Allan Melvin.

"I'm shocked and saddened! I've lost a wonderful friend and colleague," Henderson said in a statement Sunday.

'Brady' TV series, movies

"The Brady Bunch" had a successful run until 1974, but it didn't die then. It returned as "The Brady Bunch Hour" (1977), "The Brady Brides" (1981) and "The Bradys" (1990). It even appeared as a Saturday morning spin-off (1972-74).

"The Brady Bunch Movie," with Shelley Long and Gary Cole as the parents, was a surprise box-office hit in 1995. It had another actress as Alice, but Ms. Davis appeared in a bit part as a trucker. It was followed the next year - without Ms. Davis - by a less successful "A Very Brady Sequel."

Older TV viewers remember Ms. Davis for another non-glamorous role, on "The Bob Cummings Show," also known as "Love That Bob." She played Schultzy, the assistant to Cummings' character, a handsome, swinging bachelor photographer always chasing beautiful women.

It brought Ms. Davis supporting actress Emmy Awards in 1958 and 1959.

After the series ended in 1959, she appeared in such movies as "A Man Called Peter," ''Lover Come Back" and "All Hands on Deck." During layoffs she played in summer stock.

Between her two better-known shows, she played a gym teacher at an exclusive girls' school in 1965-66 in "The John Forsythe Show."

She also toured with the USO to entertain U.S. troops in Korea and elsewhere.

She was born Ann Bradford Davis in 1926, in Schenectady, N.Y., and grew up in Erie, Pa. She took to using her middle initial because "just plain Ann Davis goes by pretty fast."

She was stagestruck since the age of 6 when she and her twin sister, Harriet, earned $2 with their puppet show. She attended the University of Michigan, joking that she was a premed student "until I discovered chemistry."

Paying dues in nightclubs

She graduated in 1948 with a degree in theater and later joined a repertory theater in Erie. She told the Associated Press in 1993 that she got her big break while doing a cabaret act in Los Angeles, singing and telling jokes.

"Somebody said, 'Get your agent to call the new Bob Cummings show. They're looking for a funny lady.' Within three hours I had the job. That was January 1955. I had such fun with that show.

"I did a couple of pilots that didn't sell, a few movies and one year of nightclub work, which I hated. Then I did the pilot of 'The Brady Bunch' and never had to do another nightclub."

In 1993, Ms. Davis returned to the theater, joining the touring cast of "Crazy for You," a musical featuring the songs of George and Ira Gershwin.

Ms. Davis never married, saying she never found a man who was more interesting than your career. "By the time I started to get interested" in finding someone, she told the Chicago Sun-Times, "all the good ones were taken."
